Um i would need more details
But i thing you would add those together
x+y=10
x-y=8, x=y+8
y+8+y=10
2y=2
y=1
So, x=10-y=10-1=9.
Numbers Would be 9 and 1.
Answer:
2 sqrt(2x-1)
Step-by-step explanation:
f(x) = sqrt( x+9)
g(x) = 8x-13
f(g(x))
place the function g(x) in for x in f(x)
f(g(x)) = sqrt(8x-13+9)
Combine like terms
f(g(x)) = sqrt(8x-4)
Factor out 4
f(g(x)) = sqrt(4*(2x-1)
2 sqrt(2x-1)
Answer:
14) x = 30°
15) x = 50°
Step-by-step explanation:
14) 60 + x = 90
x = 90 - 60
x = 30°
15) 130 + x = 180
x = 180 - 130
x = 50°
Hope this helps
Answer:
It would be True
Step-by-step explanation:
2+5x = -8
SUBTACT 2 on both sides and it would look like this:
5x = -8 - (2)
5X= -10
then DIVIDE 5 both side to get "X" ALONE,
x= -10/5
then divide -10 with 5
equal to:
x = -2
